5 fadhbanna cosúil le:
28 km = 300 m =
Roinn
Cóipeáladh go dtí an ghearrthaisce
28mk=300m
Tá an chothromóid i bhfoirm chaighdeánach.
\frac{28mk}{28m}=\frac{300m}{28m}
Roinn an dá thaobh faoi 28m.
k=\frac{300m}{28m}
Má roinntear é faoi 28m cuirtear an iolrúchán faoi 28m ar ceal.
k=\frac{75}{7}
Roinn 300m faoi 28m.
28km-300m=0
Bain 300m ón dá thaobh.
\left(28k-300\right)m=0
Comhcheangail na téarmaí ar fad ina bhfuil m.
m=0
Roinn 0 faoi 28k-300.
